Abstract
In this work, nanocomposites of hexagon shaped Fe2O3 decorating few layered graphene sheets was prepared as an effective and stable heterogeneous Fenton catalyst for the efficient degradation of methylene blue (MB) dye the degradation capability of the prepared. The results indicated that the fast removal of dyes follow second order kinetics with high correlation coefficient values (r2 > 0.95). The plausible reaction process for better understanding the nature of reactive oxidation species involved in the Fenton reaction were also presented. The exceptional degrading ability and adsorption of nanocomposites substantiated their potential for wastewater remediation.
